4 BATTERY-FILLING FUNNEL.

Specification of Letters Batent. Patented Jan, 13, 1914,

Application filed March 18, 1913. SerialNo. 755,231.

To all whom it may concern:

ing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements inBattery-Filling Funnels, of which the following is a specification.

' This invention relates ple and effective operating means .in con- Inel that may be utilized for filling purposes nection with a funnel thatwill instantly give information by means of a i fl when the battery cellhas received asuificient quantity oi. the electrolyte liquid inaccordance with a predetermined arrangement and thereby prevent overflowof the liquid and contact thereof with the metal or iron of the cell toavoid corrosion and also obviate destruction of the wood portion of thecell and overcome yany tendency to creation of electrolysis in othercells that may be close to theone that is filled.

A further object of the invention is to provide a simple form of batteryfilling funin darkness or where there is very little light withoutliability of s billing the electrolyte liquid or splashing'the same overthe upper portion of the cell being filled and serving as means tomaterially reduce the number of operatives usually required underpresent methods in filling or replenishing battery cells withelectrolyte liquid; I 4 With these and other objects and advantages inview the invention consists in the construction and arrangement'oftheseveral parts which will bemore fully hereinafter described andclaimed.

In theydrawinf: Figurel is a sectional view through a unnel embodyingthe fea-,

tures of the invention and showingthe same applied to abattery celldiagrammatically represented. Fig. 2 is aside elevation of the improvedfunnel. Fig. 3 is a bottom plan view partially broken away. Fig. 1 is adetail sectional view showing a part of the buzzer which constitutes thesignaling means and a part of the connections therefor. The numeral 5'designates a; battery .cell which may be of any construction adapted Ito receive an electrolyte liquid and having Be it known tnat we, CHARLESO. KEAGY, BARTON" K. TOLLINGER, and VVAL'TER H.- BEATTY, citizens of theUnited States, residthe usual binding posts, only one, 6, of which isshown and constituting the positive terminal or connecting means. Theform of the battery cell is not essential, nor is it material as to theprecise nature of the opening or inlet for the electrolyte fluid, and itwill be'understood that the improved battery filling funnel is notconfined in its use to any to a battery fillingfunnel adapted for usevin filling electric batteries with electrolyte liquid, and the primaryobject of the same is to provide a simparticular form of cell. i

The improved funnel embodies the usual inverted frusto-conical body 7having a nozzle or cylindrical outlet extremity 8, and to prevent theoverflow of the liquid from the funnel body at the top of the latter anannulus or guard 9 is secured thereto and overcomes any tendency tosplashing or running over of the electrolyte liquid at thetop of thefunnel. Extending downwardly over a portion of the funnel body andthroughout the length of the nozzle 8 is a conduit or tube attachmentlOwhich is open at its lower end and communicates at its upper end withthe bottom of a casing or inclosure 11 in which the signal or alarm 12is mounted and consists'in this instance of the well known form ofbuzzer. It will be understood, how- 'ever, that any other suitablesignal device may be used, but a buzzer is preferred in view of itssimplicity of application and operation. The casing 11, is set in theupper portion of the body of the funnelas shown by- Fig. 1, .but doesnot interfere with the function of the latter; and the outer side of thecasing has a handle or grip 13 attached thereto for convenience inapplying and removing the funnel as an entirety and also in'transportingthe said funnel from one place toanother. Within the conduit or pipe 10an insulated wire 14 is mounted and terminates coincidcntly with thebottomof the tube, the wire being slightly projected to provide acontact point 15', the said contact point being tipped with silver. Theinsulated wire 141 is referably copper and con- -nects with a bin iiigpost 16 in the lower portion of the casing 11 and carried by'a part ofthe buzzer so as to establish electrical connection with the magnet orcoils of the latter. The armature, when the funnel is in use,isconnected. by a wire 17 with the positive post or connection 6.

' In the use of the improved battery filling funnel the nozzle 8 isinserted in the inlet opening of the cell any desired distance or 2O 1readily constructed at a minimum ex ense in accordance with the heightthe electrolyte liquid is to assume in the cell, and the wire .17 istemporarily attached or connected up to the post 6. The liquid is thenpoured into the battery through the funnel and when the liquid reaches aheightwhere it will come in contact with the silver tipped end orterminal of the" copper wire it forms a complete circuit and operatesthe buzzer 12. The operation of the buzzer 1nforms the person fillingthe battery that the liquid is within the desired distance from the topof the cell and the supply of the liquid to the funnel will be stoppedor the sizes.

person filling the battery will cease to pour any more of the liquidinto the funnel, .and overflow at the top portion of the battery will beprevented.

,The improved battery filling funnel is simple in its organization andmay be by simply applying the conduit or tu e 10 and inserting thecasing 12 carrying the buzzer or signaling device in the body of thefunnel, as shown in the drawing. The

funnel is light and readily portable and the parts thereof will notbecome easily disarrangedor injured and consequently the funnel as anentirety will be strong and durable.

It will be understood that the proportions of the parts of the funnel aswell as the improved features may be modified and varied at will toaccommodate cells of diiferent What is claimed is: 4 1. Abattery fillingfunnel comprising a funnel shaped body having a nozzle with a tubularinclosure extending downwardly over a portion of the body and fullythroughoutvthe length of the nozzle, a casing carried by the funnel bodyandhaving an electrically operated signaling device therein, anelectrical connection attached to the signaling device andextendingexteriorly'of the casing and adapted to be attached to one of thepolesof a battery, and an insulated Wire conductor extending throughthetubular inclosure and connected to the signaling device the conductorbeing out of metallic contact with any part of the tubular inclosure andthe nozzle and having a terminal exposed solely at its lower end belowthe lower end of the nozzle.

2. A battery filling funnel comprising. a funnel shaped body having anozzle, an inclosed insulated wire conductor extending full length ofthe nozzle and over a portion of the body of the funnel, the saidinsulated wire conductor beingout of metallic contact with any part ofthe nozzle or body of the funnel and exposed solely at its lower endbelow the lower end of the nozzle, a casin mounted in the upper part ofthe body an having an electrical signaling device therein, the conductorbeing connected to the signaling device, and another electricalconducbeing inclosed and carried with the funnel' as a part of theorganization thereof, and another electrical conductor attached to thesignaling device and adapted to be con nected to one of the poles of thebattery into which the nozzle is inserted.

.In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
